PMIC (Power Management Integrated Circuit) supervisors play an important role in providing control and monitoring of power supplies and microprocessors. The AS1906C23-T is a PMIC supervisor from Analog Devices specifically designed for monitoring of power and microprocessor induced noise. The device features protection against brownouts, as well as amplified current limit protection.

The supervisor\'s primary application field is automotive, such as in powertrain and in-cabin applications. It provides an ideal solution for supervisory control in modern microprocessor applications, including memory, microcontrollers and various other high-performance applications. It can also be used in non-automotive applications, such as industrial, medical and consumer applications.

The AS1906C23-T is a high-speed supervisor with a wide range of features. It includes an 8-bit general-purpose I/O register, an 8-bit watchdog timer and an 8-bit analog-to-digital converter (ADC). The supervisor also includes a power-on reset (POR) and an adjustable preset watchdog time-out (WDT). It has an optional over-current protection, as well as latched power-good (LPG) output.

The AS1906C23-T includes a programmable watchdog timer for monitoring the CPU, memory, or other peripherals up to the maximum of 16 seconds. It also offers a programmable timeout delay weak reset (TDR), which can help detect a stuck processor, prevent ASIC locking, and such. The supervisor also features a precision voltage detector (PVD) which provides brownout protection to the system.

In addition, the AS1906C23-T is designed with a variety of other features to help minimize power-supply related noise, including over-current protection (OCP), adjustable current limit protection (CLP), over-voltage protection (OVP), and under-voltage protection (UVP). OCP is an important protection mechanism as it helps to protect against over-voltage situations, especially in high-powered systems where there are devices that do not function optimally at certain levels of current. CLP provides a limitation of maximum power-supply current to the system, preventing it from exceeding levels that could cause damage. Similarly, OVP and UVP provide protection against over-voltage and under-voltage levels, too.

The AS1906C23-T is a high-performance power supply supervisor with a multitude of features and options. It provides protection against brownouts, over-current, over-voltage, and under-voltage, offering an ideal solution for a wide range of applications. The supervisors wide range of features and sophisticated programmability make it an attractive choice for automotive, industrial, medical, and consumer applications.
